The thickness of the pipe will effect the loss rate. Best thing to do is buy thermal isulating foam, normally comes in tubes will a slit down one side so it can be slid over the pipe easily. Also depending on the the fluid inside the conduit ( pipe ) and diameter, ambient temp, and location, you may be able to use a product such as heat trace. It is an electrical wrap that uses voltage and amperage to create heat to shield from the outer elements...

I've seen fittings for that situation in the plumbing section at home depot. Most hardware stores should have those fittings. I would be careful not to heat up the PVC too muc…h if you're soldering to the copper. You could use copperbond epoxy instead of soldering next to the PVC.

You will want to put a length of copper into the fitting and solder it before you put it on the galvanised so that you don't cook out the pipe dope. >>they also could have s…oldiered on a flange on copper and thread on galvanized pipe.would have been another choice

In some applications, copper pipe can be TIG or MIG welded to copper pipe or to fittings. One example might be in antenna construction, but this is not what we usually encount…er. Normally we braze or solder copper pipe to other copper pipe. We can also use a number of mechanical connections like compression fittings. Flare fittings are an example of this.

you have first to know the thermal conductivity of PPR that you are dealing with. normally, this is in range between 0.1 to 0.24 W/MK .then you apply this formula Q(IN WATTS) …=Thermal Conductivity/MK)*A( surface area for the pipe M2 )temperature difference between fluid inside pipe and temprture of pipe surface K)/(thickness of the pipe M)

The copper should fit in the Pex fitting. My mistake, Pex uses the crimp rings. There is a coupling and other fitting that you just push the pipe into and it grabs and seal th…e pipe. Pex, pvc, copper, all will fit. Just use a coupling between the copper and the pex. I had my doubts the first time I used this, but it does work and doesn't leak. Just make sure that the pipe bottoms out in the connection.

Used for inspection. Heat numbers make it possible to trace pipe from spools fabricated on a job to material documentation from a given melt. The matching documents will tell …when and where the pipe was made, the material used and the pipe grade etc.

Modern seamless pipe is extruded. The process starts wit a large cylindrical ingot like a big fat copper washer being forced through a a smaller diameter die to create a small…er diameter but longer tube. This new tube is put through a similar process producing even smaller diameter and longer.tube and so on until the desired size is attained. Generally the process is continuous such that one long continuous tube is produced that can be travelling at extremely high speeds even though the input stage is quite slow. Each size reduction accelerates the product
